Fatigue Crack Growth under Non-Proportional Mixed Mode Loading in Rail and Wheel Steel Part 2: Sequential Mode I and Mode III Loading

Applied Sciences, 2019
Rolling contact fatigue cracks in rail and wheel undergo non-proportional mixed mode I/II/III loading. Fatigue tests were performed to determine the coplanar and branch crack growth rates on these materials.

Fractographic Study on Mode II and Mode III SCC Crack Growth in Al-Zn-Mg Alloy

Journal of the Society of Materials Science, Japan, 1984
A fractographic study on mode II and mode III static- and cyclic-SCC crack growth in 3.5% NaCl solution has been carried out for a high-strength Al-Zn-Mg alloy. Static- and cyclic-SCC crack growth was introduced under mode II and mode III loads. Unlike the mode I SCC, the fracture surface morphologies of mode II and mode III SCC were characterized by ...

Analysis of Mixed Mode II/III Crack in Bilayered Composite Beam

Journal of Theoretical and Applied Mechanics, 2012
Abstract Mixed mode II/III crack investigation in cantilever bilayered unidirectional fiber reinforced composite beam is reported. The crack is situated between the layers. The two crack arms have different widths. Formula for the strain energy release rate is obtained by the linear elastic fracture mechanics methods using the magnitude of the ...
